DEVICE FOR sECuaING DOORS.

SPECIFICATION'Orming part ofLetters Patent No. 327,238, dated September 29, 1885.

` Application filed July 3l, 1885. No model.)

To @Zi whom it may concern:

Beit known that we, JOHN W. CLOUD, of Altoona, Blaincounty, State of Pennsylvania, and AXEL S. VOG-T, a subject of the King of Sweden, residingin Altoona, Blair county, State of Pennsylvania, have invented a new and useful Device for Securing Doors, of which the following is a full and true description, reference being had to the accompanying drawings, which form a part of this specification.

The object of our invention is to enable the doors of refrigerator-cars and other compartments which it is desirable to secure hermetically to be easily and securely closed. and sealed air-tight. This weaecomplish by means of the devices hereinafter described, and by which the door or doors are caused to press against elastic packing interposed between their edges and the framing or other surfaces against which they rest.

Reference being had to the drawings,which illustrate our invention as applied toa refrigeratorcar, Figurel is a side view from outside of our device, a portion of the outer sheathing of the door beingeut away to show the plate E. Fig. 2 is a vertical section through the doorfastener. Fig. 3 is a side View ofthe door and fastenerfrom inside, and Fig. 4 is a plan view of the doors and fastening devices, showing the elastic packing.

A is a cross-bar adapted' to be dropped into and held by sockets H H on the door-posts.

B B are the doors, which are made to lap' over each other and over the frame at top and bottoni. They may be made to lap the side posts or not, as 'may be desired, and wherever the doors come in contact With the frame or with each ether. if more than one is used) they are padded with an elastic material or packing, as shown atb b b; or, if desired, the packing may be attached to the frame instead of to the door.

having its inner end bent at right angles,or so as to engage with the bar A-when turned in its direction. At its outer .end the rod Gis as shown in Figs. 1 and 2. 'By this construc- C is. a rod` passing through the door -Byarid the cross-bar A, the bolt e also serving asa stop- `for the catch on the rod C.

The operation of this device is asfoliows: The cross bar A is first placed across the doorway, resting in the`sockets H H. The doors are then closed and the rod C rotated by means of its handle G, so that its bent end' will passv down into the slot in the bar A. The wheel D is then revolved and the doors thus screwed np tightly against their frames and each other,

the compression of the elastic packing making the joints air-tight.

In opening the doors, the tight joints may be loosened" by turning the wheel D in the other direction,which will not onlyloosen the pressure holding the doors together, but will, if continued, force the doors outward and away from their frames. When the doors are loose enough to pull open, the rod C is again turned4 by its handle, so that it will no 'longer engage with the cross-bar.

It will of course be obvious-that the crossbar A may, if desired, be set vertically instead of horizontally, or a fixed post or brace may be used instead of a movable one, and that one door may besecured according to our invention as well as two, and also that a slidin door may be provided with elastic packing and made to iit hermetieally in its frame by means of pressure applied by means of our device. v

' The lapping joints between the doorand its frame, or between two doors, may be beveled, as shown, or rabbeted, if preferred.

Having now described our invention, what.

we claim as new, and desire to secure by LetL ters Patent, is

1. In combination with a door so constructroo,

ed and placed .in its :trannel as to hermetically close it when pressure is applied, a threaded rod passing'through the doorandhaving a projection on its inner end for .grappling a rigid brace, and a threaded nut fitting-on the thread of the rod secured in the .door and provided with a wheel or other handlev for turning it, by means of which the door may be caused to pressrxnly against its frame, substantially as shown and described'.

2. In combination with a door so constructed and placed in its frame as to hermetically close it when pressure is y applied, a threaded rod passing through the door and having a projection on its inner endforgrappling a rigid brace, and a` handle 011 its outer end, whereby it maybe turned to engage and disengage it, and a threaded nutiitting on the thread of the rod secured in the door, and provided with a wheel vor other handle for turning it, by means of which the door may be caused to press firmly against its frame, substantially as shown and described.

3; In combination with a door so construct ed'a'nd placed in its frame as to hermetieally close it When.V pressure is applied, a threaded rod passing through the door and having a projection on its inner end for grappling'` a rigid brace', and a pivoted or hinged handle` on its-outer end, whereby it may be turned to JNO.
